[70] A point on the northern coast of Misamis province.

[71] Referring to Leo VI, Emperor of the East, styled “the Philosopher” and “the Wise;” he occupied the throne of Constantinople from 886 to 911 A.D.  He wrote several books, among which is a treatise on military tactics, which was published by J. Meursius, at Leyden, in 1612.

[72] The islands in the Calamianes and Cuyos groups number one hundred and forty-five that are charted, besides nearly sixty that are uncharted.  See descriptions of these groups in U.  S. Gazetteer of Philippine Islands, pp. 412-415, 480-484.  The names Calamian and Busuanga are now applied to separate islands, the largest, of the Calamianes group.

[73] The bird here referred to (Collocalia troglodites) is a specie of swift; the nests, composed of a gelatinous secretion from the salivary glands in the mouths of the birds, sell at high price almost their weight in gold, when fresh and clean.  The best nests are obtained on the precipitous sides of the Penon de Coron, between Culion and Busuanga, where the natives gather them at no little personal risk.  The nests are known to commerce as salangana. (U.  S. Gazetteer of Philippine Islands, pp. 170, 482.)

Delgado says (Hist. de Filipinas, p. 821) that the material used by the bird is a species of seaweed, called ngoso, or another called lano—­and not, as Colin and San Antonio would have it, the foam of the sea.  See ut supra, pp. 727, 728, and 822.

[74] The balate—­also known as “sea slug,” “sea cucumber,” “beche de mer,” and commercially as “trepang”—­is a slug (Holothuria edulis) used as food in the Eastern Archipelago and in China, in which country it is regarded as a delicacy by the wealthy classes, and brings from seven to fifty cents a pound in the markets. (See U.  S. Gazetteer of Philippine Islands, pp. 482, 483.) Delgado, writing in 1754, says (p. 935) that in Manila the dried balate was usually worth thirty-five to forty (or even more) silver pesos a pico (or pecul; equivalent, in the Philippines, to 137.9 U.S. pounds).

[75] “Better known as Penon de Coron ("Crown Peak"); a small, rocky island off the eastern end of Busuanga Island, famous for the fine quality of the edible bird’s-nests found there.

[76] Apparently the present Calamian island is here referred to; its chief town is Culion.

[77] Now known as Palawan; its northern part forms the province of Paragua, which includes many dependent islands lying near it.
